FORMNG 0R PROFILE TEMPLATE.

Application filed November 14,1925, Serial No. 69,057, and in GreatBritain October 6, 1925.

This invention relates to forming or prolile templates and refers moreparticularly to that type of template which comprises a number of metalstrips or the likermounted in a clamp or holder and capable of beingslid or moved and set to a desired shape as for example when placed andpressed into contact with an article t0 produce a representation of theprofile or shape of 'the article.

vWith such templates difliculty is experienced sometimes in obtaining anaccurate profile of an article due to the fact that there is a tendencyto press the metal strips unevenly against the article Whose prole orshape it is desired to obtain.

Now the main object of the present invention is to provide an improvedtemplate by v means of which an accurate profile of an article can beobtained. i i

lVith this end inview and such others as may hereinafter appear or areincidental thereto the invention may be said to comprise a forming orprofile template having a number of metal strips or the like mounted ina clamp provided with means whereby said clamp and strips can be movedvon a supporting member in such manner that the strips can be pressedevenly against the article the profile or shape of which it is desiredto obtain said supporting member being if desired provided with meansfor engaging said article.

ln a preferred embodiment of the invention the improved templatecomprises a number of strips, needles, yor the like of meta-l or othersuitable material located between guide pieces and slidably mountedwithin a clamp comprising an upper and lower member adjustably andresiliently secured together by means of thumb screws or the like.

For the purpose of pressing the ymetal strips evenly against an articlethe proiile or shape of which it is desired to obtain the said clamp isconveniently mounted yon Va supporting member preferably of bow or Ushape the legs of which are formed as or provided with racks which areengaged by pinions or gear wheels mounted on the clamp between the upperand lower members and capable of being rotated by means of thumb nuts.

1 The supporting member is preferably provided with adjusting screwswhich can be caused to engage the article the prolile or shape of whichis being obtained and if desired a spirit level may be mounted on theupper member of the clamp.

1n order that the invention may clearly understood reference will now bemade to the accompanying drawings wherein a preferred embodiment hasbeen illustrated by way of example. f

F ig. 1 illustrates a plan view of the improved template and Fig. 2 is asectional view on the line 2-2 of Fig. 1.

Referring to the drawings wherein the same reference numerals indicatethe same or similar parts the improved template comprises a clamp 1formed of an upper member 2 and a lower member 3 the said members beingresiliently secured together by thumb screws 4 and springs 5.

Located between the members 2- and 3 of th-e clamp are a number ofstrips, 'needles7 or the` like 6 of metal or other suitable material thesaid strips 6 being slidably mounted between guide pieces 7 havingbacking strips 8 in contact therewith.

For the purpose of pressing the .strips 6 evenly against an article theprofile or shape of which it is desired to obtain the said clamp 1 ismounted conveniently on a sup* porting member 9 of bow or U shape thelegs 10 and 11 of which are provided with racks 12 and 13 with whichpinions 141. and 15 engage the said pinions being located between themembers 2 and 3 of the clamp 1 and secured to short spindles 16 and 17which can be rotated by thumb nuts 18 and 19 also secured to saidspindles whereclamp 1 and strips 6 can be moved direction on saidsupporting member.

The supporting member 9 may be provided if desired with adjusting screws20 and 21 mounted in bosses 22 and 23 on the legs 10 and 11 respectivelythe said screws being caused to engage the article the profile or shapeof which is being obtained thereby securing the supporting member 9 inpo sition.

A `spirit level may if desired be mounted on the upper member 2 of theclamp 1.

The improved template is particularly adapted for taking the profile orshape of the flanges on the tyres of the wheels of railway and tramwayvehicles and also for taking the profiles or shapes of sections of therails but can be used for taking other profiles6 lVhen it is desired totake the profile or shape of a flange on a 'wheel ot a railway vehicletor example the adjusting screws 2O and 21 are brought i-nto engagementwith the wheel preferably with recesses previously formed on the wheelcentre oli' the wheel after which the thumb nuts 18 and 19 oontrollingthe vpinions 14 and 15 are operated and the strips 6 pressed on to thesurface of the tyre. The template is then removed and placed on a cardor the like and a sketch made of the profile.

The racls 12 -af11d13 n-iay be formed direetly on the legs and 11 or maybe formed on separate strips secured to the legs 1() and 11 as by'screw-s or the like.

What I claim and desire to secure by Letters Patent oi the Unite-dStates isr 1. A forming or profile template con'llnising 'a clamp, anumber of strips mounted in said clamp so to be capable ol being movedthereon, a supporting member for the clamp, there being toothed portionson said supporting member, toothed members on said clamp engaging saidtoothed pori tions, and means for operating said toothed member-swhereby the clamp will be moved onV the supporting mel'nber.

9,. A forming Vor profile template comprising a Aclamp composed of anupper member and a lower member, means for securing resiliently saidmembers together, gui-de pieces located between said members, movableLeiaese strips located between said guide pieces, a supporting' memberfor said clamp, there being rack portions on said supporting member,pinions on the cla-mp engaging said racl; portions and means wherebysaid pinions can be rotated.

3. A forming or profile template comprising,` a rclamp composed of anupper member and a lower member, means for resiliently securing saidinembefr-s together, zguide pieces located between said members, movablestrips located between said guide pieces, a suppertifng` member for saidclamp, there being rack portions on said member, spindles von saidcla-nip, pinions secured to said spindles between the upper and lowermembers of ythe clamp, and thumb-nuts secured to said spindles.

4. A forming or profile template comprising a clamp, strips mounted insaid clamp so as to be capable ot' being moved thereon, a bow-shapedsupporting member for the 'clan'1p, racks on said supporting member,pinions on said yclajmp, means for operating,V said Apinions wherebysaid "clamp and strips lcan be moved on the supporting` member, andadjusting screws on said supporting` member for engaging the article thepro-- ile of which it is desired to obtain.

In testimony whereol I have signed my nam-e to this speeilication.
